Brian Crower BC0900D-2 - Polaris Pro-R (21-up) Dual Spring/Steel Retainer/Seat Kit

Brian Crower SXS Engine Performance

Dual spring designed for high rpm and/or anti-lag, works with stock buckets (sizing based on the installed height of your valves). BC valve springs by PAC Racing are wound from only the highest grade, super clean, chrome silicone alloy and feature proprietary processing procedures for consistent pressures. BC retainers are machined from premium chromoly steel alloy for "set it and forget it" wear characteristics.

NOTE: This kit requires the BC3992 valve seals, in order to run the BC3992 valve seals you must change the OEM valve guides to BC3966 ( THE DUAL SPRING KIT CANNOT USE THE OEM SEAT/SEAL AND MUST USE THE SEAT THAT COMES WITH THE KIT)
